一、 Detailed Explanation of the Core Interface and Workspace

《ATOM RPG: Post-apocalyptic indie game》is an isometric role-playing game inspired by the classic 《Fallout》series. Its Mac version interface has been optimized and has good compatibility with the macOS system. The game interface is mainly divided into the following core areas:

Main Game View Area: Located in the center of the screen, it presents the game world from an isometric perspective. This is the main area where players observe the environment, move, and engage in combat.
Character Portrait and Status Bar: Usually located in the lower left corner of the screen. It displays the character portrait, health points (HP), action points (AP), and radiation level. Click the portrait or press the C key to open the detailed character panel.
Quick Item Bar: Located at the bottom center of the screen. Up to 8 quick slots can be set; simply drag items or skill icons into them. During combat, you can use the number keys 1-8 to use them quickly.
Action Button/Mode Selection Bar: Located in the lower right corner of the screen. It contains core interaction buttons such as “Combat Mode,” “Sneak Mode,” “Dialogue,” “Examine,” and “Cancel Action.” Their states change dynamically according to the game situation (such as combat or exploration).

Mini-map and Log Notifications: The mini-map is located in the upper right corner of the screen, displaying your current location, explored areas, and key landmarks. Below it, task updates, combat logs, and other important information will scroll.

UI Customization Tip: Most UI elements (such as the hotbar and status bar) have fixed positions, but the game offers various cursor styles and color scheme options that can be adjusted in “Settings” -> “Gameplay” to suit different players’ visual preferences.

II. Complete Walkthrough: From Start to Export

Step 1: Launching the Game and Main Menu

Double-click the game application to launch it. After entering the main menu, the options include:

“New Game”: Create a new character and begin your adventure.
“Load Game”: Load an existing save file. The game supports quick saves and manual saves.
“Settings”: Adjust graphics, audio, controls, and gameplay options.

Controls: Use the mouse to click and select, or use the keyboard arrow keys ↑/↓ to navigate, and press Space or Enter to confirm.

Step 2: Creating a Character

After selecting “New Game,” you enter the Character System (CHARACTER SYSTEM). This is a core phase that determines the gameplay and difficulty.

Allocate Attribute Points: You initially have 7 points to distribute among 6 core attributes such as Strength, Agility, Constitution, and Intelligence.
Choose Specialties and Skills: Based on your attribute allocation, the system will recommend character templates (such as “Soldier” or “Scientist”). You can also customize your own, distributing skill points across dozens of skills including “Melee,” “Firearms,” “Speech,” and “Lockpicking.”
Determine Background and Difficulty: Finally, name your character and select gender and background story. Beginners are advised to choose the “Survivor” difficulty.

Controls & Tips: Hovering the mouse over any attribute or skill will display a detailed description. Use the left mouse button to click the “+”/”-” buttons to allocate points. Press the Tab key to quickly switch between different creation panels.

Step 3: Core Gameplay Loop

Once character creation is complete, the game officially begins. The core gameplay loop is as follows:

Movement & Exploration: When not in combat, left-click a target location with the mouse to move there. Hold the left button and drag to rotate the camera.
Interaction: Hover the mouse over NPCs, containers, or objects and the cursor will change to indicate available actions (such as talk, search, or pick up). Left-click to perform the default action (such as talking to an NPC).
Dialogue & Skill Checks: During conversations, choose different dialogue branches. Options with tags like [Charisma 55%] indicate a skill check is required, and the success rate depends on your skill value.
Inventory Management: Press the I key to open the inventory bar. All items are displayed in a grid. Right-click an item to view the detailed action menu (Use, Equip, Drop, etc.). Drag items onto your character portrait or equipment slot to equip them.
Quest Tracking: Press the J key to open the quest log. The current quest will be highlighted in yellow. Quest objectives are usually automatically marked on the minimap.

Step 4: Combat Flow

Encountering enemies or initiating an attack will enter turn-based combat mode.

Entering Combat: Getting close to enemies will cause you to be detected, or you can right-click an enemy and select “Attack” to enter combat directly.
Turn Order: An initiative order bar will appear on the right side of the screen. Each character’s turn order is determined by their Dexterity attribute.
Action Points: During your turn, the available Action Points (AP) will be displayed in the center of the screen. Moving, attacking, and using items all consume AP.
Performing Actions:
- Move: Click within the green highlighted area.
- Attack: Click the “Aim” button in the lower right corner (or press the A key), then click on the enemy. The hit chance percentage and the body parts that can be hit will appear. Left-click to confirm the attack.
- Use Skills/Items: Use them from the quick bar, or open the inventory and right-click to use.
End Turn: When AP is depleted or you want to save actions, click the “End Turn” button in the lower right corner (or press the Spacebar).

Step 5: Saving and Exporting (Save Files)

The game does not have a traditional “export” function; progress is saved through the save file system.

Quick Save: At any time outside of combat or dialogue, press the F5 key. The game will overwrite the most recent quick save.
Quick Load: Press the F9 key to load the most recent quick save.
Manual Save: Press the Esc key to bring up the game menu and select “Save Game.” You can name your save and choose a save slot.
Load Save: Select “Load Game” in the game menu to browse all manual and auto-save slots and choose one.

Save File Location: Save files are stored by default in your Mac’s user directory at: ~/Library/Application Support/ATOM RPG/Saves. You can back up this folder to preserve your game progress.

III. Advanced Tips for Common Features

Efficient Highlighting: Hold down the Left Alt key to highlight all interactive objects and containers in the scene, avoiding the need to hover the mouse around searching.
Stealth Ambush: When not in combat, click the “Stealth Mode” button in the bottom right corner (or press the Ctrl key) to enter stealth. Attacking from behind an enemy triggers a “Sneak Attack,” granting a huge initiative advantage and damage bonus.
Targeting Body Parts: In combat, when using the “Aim” feature, hover the mouse over different parts of the enemy’s body (head, torso, arms, legs), and the hit chance and damage effects will change dynamically. Headshots usually deal the highest damage but have low hit chance, while attacking the legs can reduce enemy mobility.
Quick Trading: When trading with merchants, right-click on an item and select “Offer” to quickly enter the buy/sell interface without dragging.
Custom Controls: Although the game has preset Mac key bindings, you can remap most shortcuts in “Settings” -> “Controls” to suit your personal habits.
